[0025] At present, the acoustic package structure of the front wall of the automobile is mainly divided into three layers: the hard layer porous material, the impermeable layer and the soft layer porous material. Both the hard layer porous material and the soft layer porous material of the front and rear porous material layers are a single-layer material, that is, a single-porosity structure. The pore structure of a single-layer material is single, and its sound absorption coefficient-frequency curve has peaks and troughs, so a single-layer material with a single property has a larger sound absorption coefficient at the peak frequency in a wider frequency domain, and other frequencies The sound absorption coefficient is smaller .
[0026] attached by figure 1 Shown: the hard-layer porous material and the soft-layer porous material of the automobile inner front wall structure of the present invention both adopt a gradient porosity structure in which a plurality of single-layer...
